Intrinsic factor is secreted by parietal cells of the gastric glands in the stomach, where it binds with the vitamin. Thus bound, intrinsic factor protects vitamin B12 from digestion as it passes through the gastrointestinal tract and facilitates the vitamin’s absorption in the ileum of the small intestine.
Which of the following produces intrinsic factor quizlet?
Intrinsic Factor – Secreted from Parietal Cells (B12 Abs.) Pepsinogen – Secreted from Chief Cells in body of stomach (Digest Prot.)
What is an example of an intrinsic factor?
These factors include a person’s age, organ function (e.g., liver, kidney, cardiovascular), and co-morbid diseases. Finally, intrinsic factors also include characteristics that can be influenced by both genetics and a person’s physiology/pathology, such as height, body weight, and receptor sensitivity.
Where is intrinsic factor synthesized?
Intrinsic factor (IF) is synthesized in humans by the parietal cells of the fundus (fornix; upper area of the stomach) and the gastric body (area of the stomach above the angulus).
What is Castle’s intrinsic factor?

What is intrinsic factor quizlet?
Intrinsic factors. a substance by the stomach that enables the body to absorb vitamin B12 (a glycoprotein) B12. needed for red blood cells to grow. Anemia.
Where is intrinsic factor absorbed?
In the less acidic environment of the small intestine, pancreatic enzymes digest the glycoprotein carrier and vitamin B12 can then bind to intrinsic factor. This new complex is then absorbed by the epithelial cells (enterocytes) of the ileum.
Which of the following cells produce HCl and intrinsic factor quizlet?
Gastric glands produce gastric juice and are found in the mucous membrane. Glandular mucous cells secrete mucus, the chief cells secrete enzymes, mainly pepsinogen, and the parietal cells produce hydrochloric acid and the intrinsic factor.

Which of the following cells produce gastric intrinsic factor?
The intrinsic factor (IF) is a glycoprotein produced by the parietal cells (oxyntic cells) located at the gastric body and fundus.
What is intrinsic factor antibody?
Intrinsic factor antibodies are proteins produced by the immune system that are associated with pernicious anemia. This test detects intrinsic factor antibody (IF antibody) circulating in blood. Intrinsic factor is a protein produced by a type of specialized cells that line the stomach wall known as parietal cells.
